Abstract: EXTENDED ARC FURNACE AND PROCESS FOR  MELTING PARTICULATE CHARGE THEREIN                    ABSTRACT OF THE DISCLOSURE           The furnace and process disclosed herein comprise an extended arc furnace having at least one electrode with an axial opening therein through which an appropriate gas, such as argon, may be fed into the extended arc, and a substantially vertical reaction zone above the extended arc through which a particulate charge is fed by gravity into the extended arc zone and in its downward course through the reaction zone the particulate charge is heated and, if desired, a reaction such as reduction may be effected.  The rate of gas flow upward in the reaction zone is slow enough to permit free falling of the particulate charge but fast enough to suspend the particles for the heating and reaction time desired.  The axial electrode opening or openings are of a size to permit creation of a stabilized extended arc and to give reduced electrode consumption, improved current and voltage wave forms, and the furnace power may be modulated by changing either the rate of gas flow or the composition of the gas.  The feeding of the gas internally into the arc gives the extended arc a stability not achievable by other methods of feeding the gas to the arc volume.

Abstract: ABSTRACT OF THE DISCLOSURE           Gaseous mixtures comprising principally H2 and CO are mace by the noncatalytic partial oxidation of a hydrocarbonaceous fuel ? the reaction zone of a gas generator in the absence of supplemental H2O other than any which may be produced by the process or that which may be initially present in the reactants as an impurity.          Supplemental NH3 in an amount in the range of about 0.01 -1.00 lbs. of NH3 per lb. of hydrocarbonaceous fuel is introduced into the reaction zone as a temperature moderator.  Reducing gas may be produced thereby at a lower reaction temperature i.e. preferably in the range of about 1500 to 3500°F, and a pressure in the range of about 1-350 atmospheres, and with an improved quality.          Thus, the effluent gas stream from the reaction zone may have a reducing ratio e.g. mole ratio (H2+CO)/(H2O+CO2) of at least about 10, and usually in the range of about 15 to 100.

Abstract: Title of the Invention THERMAL PRINTER SYSTEMS          Abstract of the Invention The present systems are comprised of a means for generating heated air and a means for controlling the ap-plication of the heated air to a thermally sensitive re-cording medium,  In one such system air is heated by pass-ing it through channels, the walls of which are heated by the passage of an electric current through resistive films, which films are deposited along the length of the channels.          The controlled application of the heated air to a thermally sensitive medium is accomplished by positioning a deflection means between the heated air path and the medium, which de-flection means, when activated, allows the heated air to impinge on the medium and when deactivated deflects the heated air from the medium.

Abstract: PERIODIC SEQUENCE GENERATORS USING                ORDINARY ARITHMETIC     Abstract of the Disclosure Dislcosed are signal generators for developing multilevel output signal sequences of a preselected period of repetition.  In their general form, the generators comprise a shift register capable of storing multilevel signals, and feedback means.  The feedback means multiply the output signal of prescribed shift register stages by selected integers, add the multiplied signals in nonmodulo arithmetic, and apply the added signals to the first stage of the shift register.  The multiplying integers within the feedback means are selected to cause the characteristic functions of the signal generator to be a cyclotomic polynomial.  For descriptive convenience, the disclosed generator is termed a "cyclotomic circuit."  The disclosed cyclotomic circuits are particularly useful in a minimum memory, prescribed-period, signal generator applications.          The minimum memory is achieved by separating the prescribed period into power-of-prime factors, and by associating with each factor a cyclotomic circuit.  Each cyclotomic circuit develops a subsequence signal of a period equal to the power-of-prime factor, and the subsequence signals are combined in a transversal network, responsive to the cyclotomic circuits, to form the desired prescribed period sequence signal.  Advantageously, the multiplying feedback integers of cyclotomic circuits of power-of-prime periods are limited to 0, 1, and -1.

Abstract: FILTER APPARATUS AND METHOD                     ABSTRACT OF THE DISCLOSURE     A filtration method and apparatus for removing contaminants from liquids, including a deep bed filter comprised of either a single media layer or of two or more vertically superimposed, substantially distinct, contiguous layers of filter material. In the plural layer deep bed filters the lower layers typically consist of materials such as sand or anthracite, which are inherently comprised of nonuniform filter granules, even when graded or sieved to within a fairly restricted mesh size range. The upper layer in the plural layer filters is comprised of filter media granules having substantially identical configurations and sizes to achieve a high layer porosity for reducing the rate of back pressure buildup during the filtration cycle. Additionally, the media granules of the upper layer preferably have a specific gravity of between about 1.05 and 1.4, are preferentially hydrophilic, i.e., water-wetted, as opposed to preferentially oleophilic, and are preferentially cylindrical. One specific example of a filter material having all these characteristics includes hollow glass tubes sealed at both ends. Such materials may also be used advantageously as the sole material in a single layer deep bed filter.   The method includes backwashing the filter by flowing liquid upwardly through the filter media to expand the layer or layers substantially in situ. Afterwards, the layers are reformed. Due to the uniformity in size and shape of the filter material, the top layer is reformed with substantially the same porosity at its inlet surface as existed prior to the preceding filtration cycle .

Abstract: Abstract of the disclosure:      An improved and novel process had been found for the  esteri-fication of aminophenol, amino-benzanilide and pyrazolone com-pounds containing a .beta.-hydroxyethylsulfonyl group, by means of sulfuric acid or sulfur trioxide which improvement is characteriz-ed by that the esterification is performed in a machine which is operating with a kneading action and effect, using per mol .beta.-hydroxyethylsulfonyl compound 1 to 2.5 times the equivalent molar amount of concentrated sulfuric acid, oleum or sulfur trioxide.  This novel process has the great advantage that great amounts of sulfuric acid are saved which could charge the waste water, also in form of sodium sulfate formed after the required neutralization.  Furthermore, the .beta.-sulfatoethyl-sulfonyl compounds formed as end-products in the esterification process are prepared by this novel process in higher yields, in a higher degree of esterification rate and in a higher purity.  They are obtained in form of a powder or plastic mass from the kneading machine, which is well transportable and storable, and can advantageously used in the form of this con-sistency, without intermediate isolation of the pure .beta.-sulfato compound itself, directly ?r the preparation of azo dyestuffs which are poor of inert salts, possess a high tinctorial strength and purity.
